Application note
Configuring the STR91xFA MCU for optimum
CPU performance
Introduction
The STR91xFA series of Flash MCUs is based on an ARM966E CPU core which executes
code directly from its internal Flash memory at a rate of up to 96 MHz. To allow flexibility for
a variety of applications and power management schemes, there are many configuration
settings available to firmware during the initialization of the STR91xFA at start-up. This
application note outlines the necessary steps to ensure the STR91xFA is configured for
optimum performance for those applications which require the STR91xFA to operate at full
speed and deliver the highest performance from the CPU core and highest bandwidth of
data movement.
